Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for integrating multiple communications standards in wireless networks fail to comprehensively utilize spectrum resources and effectively coordinate network information sharing between different standards, particularly when one network is heavily loaded or a terminal has not accessed a particular standard.
Innovation Solution
A wireless network control apparatus that obtains network information from a first-standard network and instructs a second-standard network to broadcast this information to a terminal, while also managing the broadcasting of this information by the first-standard network's access points using short management frames, thereby optimizing resource usage and load management across multiple standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network information is broadcast only by the first-standard network's access points, then the broadcasting function is simple and reliable, but the spectrum resources of multiple standards cannot be comprehensively used and the load on the first-standard network increases
Solution Approach 1:
The patent introduces a network controller as an intermediary that coordinates between the first-standard network and second-standard network. The controller receives network information from the first-standard network and generates instruction information to instruct the second-standard network to broadcast this information, thereby enabling multi-standard resource utilization without direct complex interaction between the two networks
Solution Approach 2:
The patent enables the second-standard network to perform the function of broadcasting network information that traditionally only the first-standard network performed. This multi-functionality allows spectrum resources of both standards to be comprehensively used, improving overall network information sharing efficiency while distributing load
2Reliability
If the first-standard network continuously broadcasts network information, then terminals can always access the information, but the network load increases significantly
Solution Approach 1:
The patent implements periodic broadcasting where the first-standard network's access points broadcast network information at specific intervals rather than continuously. The network controller manages this periodic transmission and can supplement with on-demand broadcasting through the second-standard network when needed, reducing overall energy consumption while maintaining information availability
Solution Approach 2:
The network controller acts as an intermediary that monitors network conditions and intelligently decides when the first-standard network should broadcast and when to rely on the second-standard network, thereby optimizing energy consumption while ensuring information availability
3Productivity
If the second-standard network is used to broadcast network information, then spectrum resources are better utilized, but coordination complexity between networks increases
Solution Approach 1:
The network controller serves as a centralized intermediary that simplifies inter-network coordination. It receives network information from the first-standard network, processes it into instruction information, and manages the second-standard network's broadcasting actions. This centralized control reduces coordination complexity compared to direct peer-to-peer coordination between the two networks
Solution Approach 2:
The system implements feedback mechanisms where the network controller monitors broadcasting effectiveness and network conditions, adjusting the instruction information sent to the second-standard network accordingly. This feedback loop optimizes spectrum resource utilization while managing coordination complexity through adaptive control
